Innovative cryogenic Phase Change Material (PCM) based cold thermal energy storage for Liquid Air Energy Storage (LAES) - Numerical dynamic modelling and experimental study of a packed bed unit

Alessio Tafone et al.

Summary: Electricity storage is crucial for sustainable energy goals and integrating renewable sources, and liquid air energy storage systems depend greatly on the performance of high grade cold storage and potential of phase change materials to increase energy density. The introduction of PCM into the system mitigates thermocline effects, improves discharge efficiency, and reduces specific consumption, leading to a shorter payback period and more attractive economic investment.
